List Rules Vote up the demons you'd never want to cross paths with

Even if you’re not religious, you’ve got to give religions credit for at least one thing: they really know how to scare the living daylights out of people. Religious demons often sound more terrifying than anything a human could dream up, which isn't a bad way to keep potential sinners in line. 

This list of demons from religion includes figures from many different faiths. Christianity, Judaism, Buddhism—if it’s got an evil demon, it’s probably here. Some of these are familiar, some of them are obscure, but they’re all really scary.

Have you ever heard the phrase “I am legion,” signifying solidarity with a particular group? You probably wouldn’t have guessed that the phrase comes from the story of a possessed man in the Bible. Jesus comes across an unnamed man who is plagued by a demon. He performs an exorcism, and in order to cast the demon out, he asks it for its name.

It responds, “My name is Legion, for we are many.” This is, of course, simultaneously incredibly cool and incredibly terrifying.

An incubus is a male demon that appears to women during explicit dreams. The incubus then attacks the woman and any subsequent encounters with this demon then cause serious illness and elimination. If you think you’ve got an incubus pestering you, run, don’t walk, to your nearest exorcist.

What happens when you get it on with a mountain? If you answered, “Your union creates a race of rock children, duh,” you’re totally right, but you probably shouldn’t be cheeky, because that’s a really weird thing to know. Asag is a grotesque, hideous demon from Sumeria who leads his rock-children-things in battle. He’s so monstrous to look at, according to legend, he causes fish to boil alive.

A Dybbuk is a demon from Judaism, which clings to the soul of a living person and inhabits their body. Dybbuks are said to be the souls of those who cannot pass on to the afterlife because of the totality of their evil. They enter a person when they have sinned and not atoned, leaving a door open for demonic influence.

So if you don’t want a demon possessing you and wrecking your life, just don’t sin. Should be easy, right?
